Abstract (en)

A communication system is described for the transfer of messages between a source device and a destination device. There is provided an end-around coupled series of storage control sections, it being possible to chain a non-branching series of messages to each section. There is provided a «busy/not-busy indicator, a pointer mechanism for indicating a current storage control section for each of the devices, and a notification device which enables the source device with a «signal» in order to signal an activity. Suitable control prevents deadlock and also individual starvation situations.
